KAK doesn't just sell parts—they control manufacturing. Cold hammer forged barrels, precision-machined receivers, and quality-checked BCGs mean less variability than sourcing components from multiple vendors. Each upper receiver gets test fired before shipping.

Parts range from budget-friendly blem (blemished) deals to premium K-SPEC components. Complete uppers start around $480, while complete firearms top out near $1,600. Regular new arrival notifications and seasonal sales keep inventory rotating.
